4 FAQs about 380VEPC Communication Power Supply Rack General Contracting

What is a 380 VDC UPS system?

Typical 380 Vdc UPS system configurations are based directly on existing telecom 48 Vdc concepts, which have been applied for decades in highly reliable applications. The following diagrams illustrate how these Topology Classes can be realized with 380 Vdc based power distribution.

What is a 380 VDC-PDS infrastructure?

Specifically, the Standard defines a nominal 380 Vdc-PDS infrastructure that interconnects sources of power to devices in the data/telecom center that draw the power. Provide for the use of safe power levels, as defined by the 2011 NFPA® National Electric Code® (see Related Documents Section 2.).

Why do we need 380 VDC?

In present ac applications, this requires additional conversion stages to couple with existing electrical distribution. The adoption of 380 Vdc increases reliability, improves power quality, and eliminates the need for complex synchronization circuits associated with multi-source ac distribution.

Do 380 VDC distribution topologies meet BICSI standards?

The BICSI Standard goes on in §9.3.13.2 to state: “Direct current power systems that serve critical loads have the same availability requirements as ac power systems with additional consideration given for personal safety.” 380 Vdc distribution topologies fully meet the objective of this standard.
